It was quite a loud shaker in Tsukuba. The first Shindo four that I didn't miss by conincidence for a while. Not that I "miss" them in an emotional sense. Kind of a quake season, it seems. It's the fifth magnitude 5 or above quake in the Fukushima, Ibaraki and Chiba area in about 40 hours. Could it be foreshocks of the next big one?

It was about a Shindo 3 in Western Tokyo where I was.
The article states "5 in Tokyo", but according to JMA it was between 1 and 3 in Tokyo.
The Japan Trench extends to the Ogasawara Trench which starts to the South East of Chiba. It could be that these are related aftershocks...hopefully not foreshocks. Considering how powerful the March quake was, it's not at all surprising. Just the fact that it's made us all edgy everytime we feel a quake.
